By model
How each assistant handled Hvac Company questions.
Reading the 45 answers model by model shows how differently the three assistants treat the same hvac company questions.

It named a specific provider in 0% of answers (about 0 distinct providers per answer) and included price or cost information 26.7% of the time. ChatGPT asked a clarifying question before answering in 60% of cases, warned about red flags or scams in 13.3%, and told the buyer to verify credentials in 13.3%, averaging 487 words per answer. On the remaining cues it told the buyer to check reviews in 20%, pointed to case studies or a portfolio in 6.7%, and framed the choice around local proximity in 26.7%; a selection-criteria checklist appeared in 46.7% of its answers and a recommendation to gather multiple quotes in 33.3%.

Where they disagree
The behaviors where the choice of model changes the answer.
Question-level model disagreement is 20.7% — the average pairwise rate at which models received different binary codes across questions and behaviors. The observed rate spreads below are a separate measure showing where which assistant a hvac company buyer happens to ask matters most:
- Asks a clarifying question: from 0% (Gemini) to 73.3% (Claude) — a 73-point spread.
- Gives selection criteria: from 33.3% (Gemini) to 60% (Claude) — a 27-point spread.
- Warns about red flags or scams: from 13.3% (ChatGPT) to 40% (Claude) — a 27-point spread.
- Recommends multiple quotes: from 6.7% (Gemini) to 33.3% (ChatGPT) — a 27-point spread.
- Recommends hiring a professional: from 60% (Gemini) to 80% (ChatGPT) — a 20-point spread.
The widest single gap — asks a clarifying question, 73 points — means a hvac company buyer can receive materially different guidance on the same question depending only on which assistant they happen to open, so any visibility strategy built on a single model's behavior describes only part of the hvac company market.
Where they agree
The points of near-consensus in Hvac Company.

Trust signals
How well the models protect the hvac company buyer.

Telling the buyer to check reviews or ratings appeared in 15.6% of answers on average. Verifying credentials or certifications appeared in 15.5%. Warning about red flags or scams appeared in 28.9%.

The single least-reproduced protective signal for hvac company is "tells the buyer to verify credentials" at 15.5% on average — the clearest opening for content that supplies it, since the models are not yet reliably surfacing that guidance on their own.
Referral behavior
Do AI models name Hvac Company providers?
For service providers the decisive question is whether these systems name anyone at all. Across 45 hvac company answers, a specific provider was named in 2.2% of responses on average — roughly 0.1 distinct providers per answer. In practice the assistants behave far more as an explanatory layer than as a referral engine for hvac company: visibility comes from being the reasoning a model reproduces, not from being the named recommendation.
The question set
What these 15 Hvac Company questions cover.
The 15 questions behind every percentage on this page form a frozen hvac company (home services; buyer hiring decisions for this specific service) buyer-intent benchmark. Each was put to all 3 models once, with identical wording, so the rates above describe how the assistants handled this exact hvac company question set — not a general prior or a hand-picked subset. The full list is shown earlier on this page; the coded percentages are what those specific questions produced.
How to read this
A note on the numbers.
A percentage here is the share of a model's 15 answers in which the behavior appeared at least once — not a confidence score. Because each model answered every question exactly once on 2026-07-04, the figures describe this specific hvac company question set and snapshot rather than a general prior. The full protocol and coding rubric are documented in the study methodology.
Methodology
A controlled snapshot, documented end to end.
15 frozen benchmark questions, one expected response per model per question (ChatGPT API (gpt-5-mini), Claude API (claude-sonnet-5), Gemini API (gemini-3-flash-preview)), collected 2026-07-04 and coded against a fixed 12-behavior rubric. The pipeline validates the schema, recomputes aggregates and reports consistency issues. AI outputs vary with model version, location and time, so the figures describe this edition's exact sample and measurement window. Read the full methodology →
